BOTTLE.

Specification of Letters Patent.

Application filed December, 14, 1908. Serial No. 467,371.

To all whom it may concern:

Be it known that I, EDWIN T. GREENFIELD, a citizen of the United States,and resident of Kiamesha, county of Sullivan, and State I of New York,have made a new and useful invention in Bottles, of which the followingis a specification.

My invention is directed particularly to bottles constructed of fibrousmaterial, such, for instance, as paper, and it has for its objccts,first, to device a bottle of this character which may be so cheaplyconstructed as to make it possible to use the same commercially a'singletime only and then destroy it, thereby providing. a containing vesselwhich shall have the best possible sanitary qualifications. Second, todevise a bottle constructed of fibrous material, such as paper, whichshall have the shape or conformation of well known forms of glassbotties having the usual body, throat andneck, and in which said throatand neck shall be relatively of much greater strength than the bodyproper of the bottle, thereby simulating, as far as possible, thestructure of glass bottles by producing a bottle of relatively fragilematerial which will be capable of relatively rough usage without damagethereto, or without any possibility of re leasing the contents thereofin bottling and handling the same. Third, to devise a bottle of thecharacter indicated in which the bottom, throat and neck thereof shallpossess relatively great strength and the entire structure such as to beof minimum weight. Fourth, to devise a bottle of the character indicatedthe parts of which, before being assembled, may be shipped directly tothe user, occupying as small a space and being of as little weight aspossible, said parts being structurally so devised that the completebottle may be formed ready for filling at. the point where it is to befilled, as in a dairy, farm-house, or analogous place where suchperishable liquids as milk, cream, and the like are to be bottled andshipped to consumers. Fifth, to devise a bottle of the characterindicated which, after it is once filled, can only be opened by thepurchaser by destroying the id or cover, or sea-led portion thereof,when the liquid contained therein is to be used.

For a full and clear understanding of the invention, such as will enableothers skilled in the art to make and use the same, reference is had tothe accompanying drawings, in which,

Figure 1 represents anelevational view of a full sizedbottle embodyingall of the features of my invention. Fig. 2 is a vertical sectional viewtaken through Fig. l on the line XX and as seen looking thereat fromleft to right in the direction of the arrows. Figs. 3 and 4 aretransverse sectional views taken through Fig. 1 on the lines YY and Z-Zrespectively, and as seen looking thereat from the top toward the bottomof the drawings in the direction of the arrows.

Prior to my invention bottles or containing vessels have beenconstructed of fibrous material, such as paper, in which the entirestructure is either of cylindrical form or cone-shaped, with bottoms andtops in the nature of compressed cups made of the same material andsecured thereto in various ways. All such bottles or containing vessels,however, with which I am familiar, are either made of a single layer ofmaterial or of a plurality of layers having the same thicknessthroughout the length of the bottle. Such devices are open to the objec"on that they have not sufiicient strength, t those parts of thestructure by which they are handled, to prevent their being damaged inmarketing or shipping. Such structural devices are also open to thefurther objection that their dissimilarit to existing types ofcontaining vessels, in the nature of glass bottles for milk, cream, ordairy products generally, makes it impossible to expeditiously handlethe same as ordinary bottles are handled, namely, b the throats andnecks thereof. Such bott es are also open to the further objection thatall parts of the same are of like thickness and there is a possibilityof puncturing the bodies in ordinary manipula tion during the handlingthereof My improved bottle overcomes all of these objections and to suchan extent that it may be handled identically as glass bottles arehandled and with much less danger of the vessel being ruptured orbroken. At the same time, my novel bottle is materially lighter, therebyaffording a vessel of the character indicated which makes it farpreferable to existin glass bottles.

% roduce a bottle of the character indicate by first forming one or morethick- Patented Nov. 16, 1909.

ncssesof paper into a tube of the desired diameter to constitute thebody of the bottle and secure the edges thereof together. I then so actupon one end of this tube, through the agency of pressure and heat, asto form a series of box-plaits, which plaits are of the greatest widththroughout the length of the neck and the edges thereof are parallel.with each other, said plaits converging gradually from the lower end ofthe neck to the lower end of the throat or to the upper end of the bodyof the bottle proper. Such box plaits constitute a means of not onlye'tl'ecting greater strength to the neck and throat part of the bottle,but also of radially taking care of the surplus material whichnecessarily results from forming one end of a tube into a convergingthroat and cylindrical neck. I then secure in any preferred manner apaper cup bottom to the lower end of the body part and a strengtheningrim to the upper end of the neck, after which I provide a detachable cupshaped cap, such parts constituting the completed bottle.

Referring now to the drawings in all of which like numerals representlike parts Wherever used, 1 represents the body of the bottle which isin the nature of a paper tube made preferably of strong manila or likematerial, the length of said tube before the bottle is formed beingsubstantially the length of the completed bottle. 2 represents thethroat thereof and 3 the neck, which throat and neck are preferablyforn'ied by subjecting the upper end of the tube as hereinbefore statedto relatively great pressure between the parts of heated external andinternal molds and in such manner that when this pressure is beingeffected a plurality of strengthening ribs, preferably in the nature ofbox plaits 7, 7, are formed, the edges of which are parallel with eachother throughout the entire length of the neck and converge toward eachother from the lower end thereof to the bottom of the throat or the topof the body part proper of the bottle, as clearly illustrated in Figs.1, 3 and 4. These plaits may be formed by any desired mechanism, as, forinstance, by a heated interior metal "mold having the conformation ofthe interior of the completed bottle and by ironing down the plaits by aheated iron, such a method of construction being possible and it beingobvious that when the throat 2 and neck 3 are thus formed, said throatand neck will have an increased strength from the shoulder to the bottomof the neck' and the neck itself will be of relatively greater strength,dependent upon the size and number of the plaits. I have shown in thedrawing, four such plaits. In practice, I should prefer to make six,thus bringing the lateral parallel edges thereof relatively closertogether around the neck where the greatest strength is required. Itwill be apparent, therefore, on inspection of the draw lugs, that thethroat and neck necessarily are relatively much stronger than the bodypart 1. of the bottle and that the saline may be handled as an ordinaryglass bottle is handled. by the throat. and neck. whilein the course offilling, transporting, or use generally and without danger of injurythereto. After the body, throat and neck are thus formed a cup 4, madeof paper or other fibrous material by compression in a heated die in amanner well understood by those versed in the art of making pressedpaper articles, is inserted, bottom upward, in the bottom of the body 1,then said cup and bottom are subjected to the influence of a heatedbeading tool, so that the two parts are secured together by the jointaction of two concentric beads 8, in the manner shown in Fig. 2. The cupt may be provided with one or more corrugations t), as shown, for givingincreased strength to the bottoi'n. A mouth ring 5 is then constructedby heated dies, said ring havingdownwardly extending lips, as clearlyshown in Fig. 2. This ring is slipped over the upper portion of theneck, as shown, and it and the neck are then subjected to the action ofa heated beading instrument as was the bottom 4, so as to therebyeffectually secure said mouth ring to the upper portion of the neckthrough the agency of concentric beads, similar to the concentric heads8 at the bottom.

The entire bottle" is then subjected to a bath of molten paraflin, thusmaking it not only effectually liquid tight, but rendering it alsopractically transparent so as to enable one to inspect the liquidcontained therein. A cup-shaped cap 6 is then prepared in a heated dieand the same is of such dimension and shape as to enable one to fit itover the mouth ring 5. After the bottle. is filled, this cap which hasalso been paraflined is placed in a manipulating device or cup heated tosufficient temperature to fuse the parafiin and the cap is forced snuglyover the mouth ring 5 and allowed to seat and seal itself against thelatter. It will also be obvious that where box plaits are of such numberand width as to bring the lateral or parallel edges of the same 'aboutthe neck against each other, or in relatively close relation to eachother, the bottle will present a symmetrical appearance to that of glassbottles having throats and necks, and that bottles as thus constructedwill have increased strength against compression in handling from thetop of the body part to the lower end of the neck, and still furtherstrength throughout the entire length of the neck, thus resembling inthis feature existing types of bottles of glass and like materials.

It will be obvious that the parts-of such a bottle may be shipped to thepoint where it is desired to construct and use it, in the llt -structedin the manner Patent Office on the 14th day of December.-

1908 and bearing Serial No. 467,372.

I do not limit my invention to the specific details of constructionshown, as the essence of my invention lies in the formation of a bottlefrom one or more sheets of paper or analogous fibrous material, and ofsuch a structural formthat it resembles the well known type of glassbottles now in general use throughout the world. the most essentialfeature of my invention lying in the production of a bottle whichpossesses the qualifications hereinbefore enumerated.

It will be noted that by my improvement I have devised a bottle made ofpaper or other fibrousunaterials which simulates in all respects wellknown types of glass bot-- tles, in that the throat gradually increasesin strength from the top of the body part of the bottle to the lower endof the neck, while the latter is of greater strength in cross sectionthan either the throat or the body, so that my improved bottle haspractically all of the qualifications of strength as to those parts bywhich such bottles are ordinarily handled, as is found in well knowntypes of marketable glass bottles, and my claims hereinafter aredesigned to be of such scope as to fully protect me in the applicationof this generic idea to bottles made of materials other than glass,porcelain, pottery ware, or the like.

I laving thus described my invention what l claim and desire to secureby Letters Patent of the United States is 1. As an articlcof manufacturea paper converging from the lower end of the neck lower end of said bodypart, substal it-ially as.

described.

3. A paper bottle having a box plaited neck and throat; a tubular body;and a cupshaped bottom secured to the lower end of the body, the edgesof the box plaits being parallel throughout the length of the neck andconverging from the lower end thereofthroughout the length of thethroat, substantially as described.

4. As anarticle of manufacture a bottle constructed of paper andembracing a tubular body part, a bottom, a throat, a neck, and astrengthening ring for the neck; the

neck and throat being provided with box plaits, the outer edges of whichare arallel throughout the length of the neck, w ile the likeedges ofthe plaits for the throat converge from the bottom of the neck to thetop of the body part, the bottom being secured to the lower end thereofby concentric beads and the strengthening ring similarly secured to theneck, substantially as described.

5. As an article of manufacture a bottle constructed of paper andembracing a tubular body part,-a bottom, a throat, a neck. and astrengthening ring for the neck; the neck and throat being rovided withboxplaits, the outer edges 0 which are parallel throughout the length ofthe neck, while the like edges of the plaits for the throat convergefrom the bottom or the neck to the top of the body part, the bottombeing secured to the lower end thereof by concentric beads and thestrengthening ring similarly secured to the neck; together with a cupshaped cap adapted to act as a cover for the bottle, substantially asdescribed.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
